C.OIN-CONTROLLED LOCK.

Specification of Letters Patent.

Application led August 14, 1907.

Serial No. 388,442.

To all whom 'it may concern:

Be it known that I, EDWIN A. RICHARD- residinnr at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Coin-Controlled Lock, of which the following is a specification,

The object of th1s invention is to provide a new and improved locking mechanism which will be controlled by a com so that when the coin is inserted, 'the lock can be o erated and the key withdrawn, and -so that W ien the key is again inserted and the lock unlocked, the 'key will 4be held in the lock and cannot be again removed until a new coin is inserted.

The mechanism can be used advantaeousl lin many locations, as for example, 1n um rella racks, whereby by inserting a nickel or ,other coin, the umbrella can be locked up, the key carried awa and when the lock is unlocked to take out t e umbrella, .the key is locked in the device.

Enough oi the essential features of the mechanism are shown in the accompanying drawing forming part of this specification to enable those skilled in the art to practice the same.

Referring to said drawing, Figure 1 is a front elevation partly in section showing the lock unlocked. Fig. 2 is a front elevation with the mechanism locked. Fig. 3 is a sectional plan view. Fig. 4 is a plan view of the two Operating disks. `Fig. 5 is a front view of the loose disk. Fig. 6 is a perspective view of the lock-operating disk. Fig. 7 is a sectional elevation illustrating the operation when a penny is inserted.

The o eration of the mechanism will be best un erstood by adetailed description thereof.

Referring to the drawing and in detail, 10 designates a box or casing which is turned or bored out to have a circular hole'. A back plate 11 and a front plate 12 are secured thereto in any suitable manner. 'lhe front plate 12 is provided with one or more of the usual keyguiding disks 13 so that only one particular key can be inserted inthe lock. A loose disk 14 is journalcd or iitted in the box or casing. This loose disk is provided with`notches 15-15, the bottoms ofwhich are inclined, as shown at 151 in Fig. 7, for a uroose hereinafter described. The disk 14 Is formed with a central hole 150 and is proi vided with lugs; 15 2 which leave a suitable slot 153 so that when the right key K 1s inserted therein, the loose disk 14 can be turned by the key.

16 designates a lock-operating disk-which is also iitted in the caslng 10. This lockoperating disk has suitable notches 17-17.

The box or casing is provided'with a coin recelvnig chute C and a colnoutlet O. The

lock-operating disk always stands so that one 'i of its notches 17 comes in re istr'a'tion with the chute C and one of its notc ies in registra tion with the outlet O, when the parts are rx unlocked position as shown in Flg. 1. The lock-operating disk 16 is -cut away and a pawl spring ,18 is inserted therein.

The casing 10 is provided with suitable notches 19-19 sov arranged that the lock-operating disk can only be turned in one direc-.

tion and that, the direction indicated by the arrows in Figs. 1 and 2. The lock-operating disk 16 is provided with two bolt operat'ing pins 20-20. f l

21 designates the sliding bolt which Wo'rk's on a guide pin 22. The olt 21 is provided with an operating arm 23 against which the pins 20-20 be'ar andwith a locking notch 230. lhe bolt 21 is normally held in retracted position by a spring 24 Vfitted on an arm 25, the ends lof the spring being secured to the casing and to the bolt 21.

The front plate 12 is provided with a `key slot 26 which in the particular arrangement illustrated, stands in horizontal 'ositioIL The lock-operating disk 16 is provi ed with a slot 27 through which the key is inserted. The slot 26 registers with the slot 27 when the bolt is in locked position, and stands at right-angles thereto when the bolt is in re tracted position.

The key K is provided with key-retaining arms 28 which can pass through vthe slot 27 in the lock-operating disk when the slots 26 and 27 are in registration. The key'cannot bc inserted in between the lugs 150 to operate the loose disk unless the arins 28 thereof pass through the lock-operating disk 16.

The device as shown is arranged to be o ierated by a nickel or five-cent iece. T e lock is shown in its normal or-u ockedposition with the ke. locked therein, in Figs. 1 and 3. When tiielnickel is .inserted in the chute C, the key K is turned to bring the notches 15 of thel loose disk 14 into registration with the slots 17 of the lock-operating disk 16, if that condition 'does not exist. When these, notches are brou ht into registration, the nickel will drop own into the loo disks 1li-16, locking the saine together as shown in Fig. 4. The key is now given a quarter turn which will bring the slot 27 into registration with the key slot 26 whereby the key can be Withdrawn leaving the bolt out, as shown in lFig. 2. As this 'action takes place, the pin 20 will run up on the arm 23 on the bolt 21 and will snap into the notch 230. ln this position of the arts, the operating disk can only be turnedp in a direction indicated byfthe arrows and the spring 24 can- 1 not pull the bolt back.

When it is desired to unlock the device, the key is inserted and given another uarter turn in the' same direction. This Wil move .the operatin pin 20 which engages the bolt 21 clear of tie operating arm 23 When the bolt 2l will iiy back under the tension of the spring 24, unlocking the lock. -'fter @his quarter turn, the parts will' be'brought back to the position shown in Fig. 1, the paWl 18 engaging one of the notches 19-19. As this takes place, the coin will come oppositev the outlet chute O and will drop out of the disks 'i4-16 so that any further rotation of the key Will not operate the disk 16. This will leave the disk 16 in normal position with the key K locked in the device from which it cannot be removed until a nickel isagain inserted.

lf a penny is dropped into the chute, when the disks la and 16 come into registration, the same will roll so as to come entirely Within the disk beingmade the width of a penny for this purpose and the disks 14 and 16 together bein made of a Width a little larger than a nicke so that a nickel will lock the parts together. By this mechanism a simple and elicient device is provided for'the purpose stated.
